UNITED STATES PATENT OFFICE.

w. II. BLOOD, OF sAN FRANCISCO, CALIFORNIA.

IMPROVED CLOTH ES-WASHING MACHINE.

Specification forming part of Letters Patent No. 41,190, dated January 12, 1864.

To all whom t may concern.'

Be it known that I, W. H. BLOOD, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Clothes-Washing Machine; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line x x, Fig. 2 5 Fig. 2, a transverse vertical section ofthe same, taken in the line y y, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

rlhis invention consists in the employment or use of a stationary concave of rollers fitted within a proper suds-box and used in connection with an oscillating yielding or elastic rubber, the same being attached to a rockshaft, the bearings of which are tted on springs and the rock-shaft provided with a treadle attachment, all arranged in such a manner as to enable clothes to be washed in an expeditious and perfect manner and without injuring the same by excessive or undue friction.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a suds-box of quadrilateral form and having inclined ends a a. This suds-box is supported at a suitable height by a proper framing, B, and within the sudsboX there is permanently secured a concave, G, which is composed of two curved plates, b b, attached one to each side of the suds-boX A, at its inner side, and having rollers c fitted between them, the journals of the rollers being allowed to rotate freely in the plates h b. At each side of thc suds-box A there is an upright, d, the upper parts of which are slotted vertically, as shown at e, and in each of these a spiral spring, D, is placed, on which the bearings E of a rockshaft F rest. The bearings E are provided with pendent pins f, which are inserted in the springs D, and to the outer ends of each bearing E a rod, G, is attached, said rods extending down and being secured to the ends of a cross-bar, H, which is underneath ghe suds-box A, and has a treadle, I, at- -tached to it.

To the rock-shaft F there is attached two pendentbars, J J, each having a head or block, g, attached to it, each head or block having a spring or elastic plate, h, secured to it, to which plates or cross-bar or rubber Kl is attached, said cross-bar or rubber having its under surface corrugated or fluted longitudinally.

To the rook-shaft F and heads or blocks g there are attached two Vshaped rods, L L, the angles or outer parts of which are connected by a cross-bar, M, which serves as a handle.

The operation is as follows: The suds-box A is provided with a requisite quantity of suds, and the clothes to be washed are placed on the concave C and underneath the crossbar or rubber K. The operator then places his foot on the treadle I and presses the rubber K down upon the clothes, and the rubber is moved back and forth by means of the handle M, which is grasped by the operator.

The handle K, in consequence ot' being attached to the elastic plates h It, is allowed to yield or give independently of any other means, and another yielding movement is allowed the rubber in consequence of the bearings E of the rock-shaft F resting upon the spiral springs D. These two yielding movements, which are allowed the rubber, admit of the latter acting upon the clothes without subjecting them to any undue friction or rubbing, and the pressure of the rubber upon the clothes may be regulated with the greatest facility by simply bearing down more or less hard upon the treadle I.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent., is-

The stationary concave of rollers C, placed within the suds-box A, in combination with the oscillating rubber K, attached to elastic plates h, and connected by pendent bars J J to a rockshaft, F, the 'bearings of which rest O11 spiral springs D and the ends or journals of which are connected to a treadle, I, all arranged substantially as and for the purpose herein set forth.
